Directions

Crust: In a bowl, stir together flour, sugar and salt. Using a pastry blender, cut butter cubes into flour mixture until pieces are pea-size. Sprinkle vinegar over flour mixture, tossing with a fork. Sprinkle 5 to 6 tablespoons cold water, 1 tablespoon at a time, over flour mixture, tossing with a fork each time until dough is moistened and crumbly. Press crumbs firmly on bottom and up sides of a 9-inch pie plate.
